GMAT Reading Comprehension (RC) | Ecoefficiency (measures to minimize environmental impact

Hi - I have a question on why C is correct

The answer choice was : C.present a concern about the possible consequences of pursuing a particular business strategy

Question : why is this correct when the author has multiple concerns --- not only one concern.

The multiple concerns were :

--- profit created and that would be lead to investing in not so efficient companies
--- Even a vastly more ecoefficient industrial system could, were it to grow much larger, generate more total waste
